IMPRCVEM ENT IN HYDRANTS.

Specification forming part of Letters Patent No.

192,336, dated VJune 26, 1877; application filed August 16, 1876.

To all whom it may concern Be it known that I, WM. KAISER, of the cityof Wilkesbarre, county of Luzerne, State of Pennsylvania, have inventeda new and useful Improvement in Hydrants, which improvement is fully setforth in the following specication, reference being Ahad to theaccompanying drawings.

The object of my invention is the construction of a hydrant at a lowprice, simple and durable in construction, which is also susceptible ofall possibly needed repairs without the necessity of digging up thesame.

In the accompanying drawings, forming part of this specification, Figurel is a per spective view of a hydrant embodying my invention. Fig. 2 isa longitudinal section of it. Fig. 3 is a transverse section of toppart, through nozzle, showing guide-ring F with cone-spring E restingthereon. Fig. 4 is a transverse section of quadrilateral part ofvalve-stem L, also corresponding cavity in screwnipple N. Fig. 5 is atop-plan view ofl valve-seat and stem. v

The construction is as follows: The case K, which, to all outwardappearancesis a rightangled elbow, has a globe shaped expansion, at thebase of which is formed the valveseat, as shown in Fig. 2, and over thevertex of said expansion the screw-thread D is cut to receive thescrew-nipple N. There is also a thread cut on the expanded part Sdirectly above, to receive a one and a quarter inch or larger tube, saidtube constituting part of the hydrant and casing, and which may be cutt0 any required length, and the same is also threaded on its upper endto receive the contracted end G of conical cap G, which has ascrew-threaded perforation at its vertex, in which revolves screw-boltA, said bolt having an enlargement, T, at itslower end, to prevent itsextraction and loss. On its upper end R is a crank or hand wheel, asshown in Figs. l and 2.

Having'described the exterior, I will now proceed with the interiorconstruction.

Hollow valve-stem L has one or more perforations on its circumference atits base, with bolt and burr on the end to receive and hold a washer ofleather or other material. Onl

projecting ring or flange a: is also a washer.

The exterior quadrilateral portion .P of valvestem L rests inside of thecorresponding cavity in nipple N, as shown. in Figs. 2 and 4, the saidvalve-stem L having a free perpendicular movement, sufficient to admit afull head of water when the same is opened. The said stem Lis, at allpositions, a wrench or key, which, if revolved horizontally, will eitherscrew or unscrew nippleN from valvecasing K, as shown in Figs. 2 and 4.The upper end of valve-stem L is turned to closely t in thecorresponding upper half of nipple N, consistent with free verticalmovement, thereby preventing leakage of water in that direction whenvalve L is only half open or closed, as shown in Fig. 2. The extremeupper end of valve-stem L is screw-threaded, on which is screwed anordinary pipe-socket, which forms a shoulder, against which screwnippleN may rest, to prevent said nipple from sliding beyond the control ofvalve-stem L, as shown in Fig. 2. Pipe Iis also screwed or otherwiseconnected to pipe-socket, 'as

shown, which pipe is cut and threaded to the proper length toreceive'the elbow B, having circular bolt shaped extension Z, said boltend resting in concave cavity of screwbolt A, -as shown in Fig. 2.

F is a metal washer or ring, through the perforation of which passespipe I, serving as a guide to said pipe in its vertical movements, andalso a seat for cone-spring E, the upper end of which presses againstelbow B, as shown in Fig. 2. Gonical cap C is made of such diameter aswill allow its free revolution around elbow B, as shown in Figs. 2 and3. Cap G has also one or more oblong perforations, V, through whichnozzle H is inserted, and the same screwed into elbow B, as shown.

Its operation is as follows: Fig. 2 shows the hydrantin the process ofclearing itself of the Water remaining in pipe I, after being closed,through perforation O in screw-nipple N and casing K, valve L being nowclosed against the ingress of water from lthe main, and, byturnin ghand-wheel R in the direction of the arrows, will release the pressureof bolt Afrom elbow B, thereby allowing cone-spring E to perform itsfunction in raising pipe I and valve-stem L perpendicularly fromvalve-seat in case K until flange X, having on its upper side a washerof leather or other material, up to and against nipple N, thereby firmlyclosing the waste-conduit, and allowing the free ingress of water fromthe main into and through valve-case K, stem L, pipe I, and nozzle H.

In making any and all possibly needed repairs, the operation is to turnoff the water at the usual stop-cock, unscrew nozzle H, then cap C fromits base G, then rescrcw nozzle H to elbow B, use it as a wrench, andturnthe same as you would unscrew any pipe, which will have the e'ect ofunscrewing nipple N from case K 3 then draw the whole interiorarrangement up and out of tube J, and, after making the necessaryrepairs, reinsert pipe I, with valve-stem L, into tube or casing J, andscrew the same in reverse order from the beginning, and turn on waterfrom the main.

Having thus fully described my invention in the foregoing specification,I claim as new and desire to secure by Letters Patent of the UnitedStates- 1. rlhe quadrilateral portion P and projecting flange a: of ahollow valve-stem, L, screwnipple N, its quadrilateral cavity u andperforation O, in combination with a valve-casin g, K, and pipe-socket1', as shown, for the purpose set forth.

2. The combination, in a valve-casing, K, having contracted portion, andscrew-thread D, of enlarged portion S, with a screw-nipple or socket, N,and hydrant casing or tube J, as shown and described, for the purposeset forth.

3. The guide-ring F, cone-spring E, concave cavity Z on bolt A, incombination with the conical casing or cap C, its base G, elbow B,discharge-pipe I, and nozzle H, all arranged as shown and described, forthe purpose set forth.

WM. KAISER.
